Design of a Book Sales Management Information System to Support Business Process Digitalization at Sidosari Wunut Tulung, Klaten

This study aims to design and implement a web-based book sales management information system to support business process digitalization at Sidosari Wunut Bookstore, Tulung, Klaten. Book data, sales transactions, and inventory were previously recorded manually, which limited the accuracy and accessibility of information. The system was developed using the Waterfall method, which comprises requirement analysis, design, implementation, verification, and maintenance. Requirements were identified through observation of the bookstore's operational processes and documented in a Software Requirements Specification (SRS) structured according to IEEE 830-1998, while the Unified Modeling Language (UML) was used to model the system. The system was implemented using JavaScript with MySQL as the database. The main contribution of this study is a documented design and working implementation that integrates book data management, sales transactions, and automatic stock updates in a single web-based system adapted to a small-scale bookstore. The novelty of this study lies in documenting the full path from an IEEE 830-1998 requirements specification and UML models to a functionally tested implementation for a small-scale bookstore, whereas the related studies reviewed focus on online sales, recommendation, or inventory analysis. System verification used black-box testing on five main pages, with 20 recorded checks. Eighteen checks passed and two failed, giving a success rate of 90%. These results indicate that the main functions of the system operate in accordance with the specified requirements, except for the two failed checks, which need correction. The study demonstrates the practical role of web-based information systems in supporting business process digitalization in small-scale bookstores and offers a reference design for similar microenterprises. Usability and user acceptance were not evaluated and remain subjects for further research.
